[0032] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] In order to better understand the purpose, structure and function of the present invention, a temperature vibration sensor of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 4 As shown, a temperature vibration sensor of the utility model includes a base 1 and an upper cover body 2 detachably arranged above the base 1. A main board 22 is also arranged inside the upper cover body 2, and the electrical connection on the main board 22 is connected to the temperature sensor 3 arranged in the base 1 through a wire 5.

[0035] The main board 22 in the upper cover body 2 is installed through the main board accommodating cavity 21 opened inside the upper cover body 2 so that it can be installed stably.

[0036] The base 1 includes a base body 11 and a sealed cavity 12 opened downward from the top of the base body 11. A sealing plate 4 capable of sealing is detachably provided at the opening of the sealed cavity 12, and the upper opening of the base body 11 can be formed into a closed space through the sealing plate 4. At the same time, a sensor accommodating cavity 13 for installing a temperature sensor 3 is opened downward from the bottom surface of the sealed cavity 12, and the temperature sensor 3 is arranged at the center of the base body 11.

[0037] The inner ring wall of the sealing cavity 12 is provided with a limiting seat 121 for supporting the sealing plate 4 , and a rubber ring 122 is provided between the limiting seat 121 and the sealing plate 4 to achieve a sealing effect.

[0038] After the wire 5 connected to one end of the temperature sensor 3 passes through the through hole 41 opened on the surface of the sealing plate 4, it can be connected to the main board 22 to realize the signal transmission of the temperature sensor 3. At the same time, when the ambient temperature of the temperature vibration sensor is installed is high, the upper cover 2 can be disassembled at this time, and then the upper cover 2 and the main board 22 can be installed at a position where the ambient temperature is relatively low, and the sealing plate 4 arranged above the base body 11 can seal and isolate the temperature sensor 3 inside the base body 11, further improving the protection of the temperature sensor 3 after its disassembly and separation.

[0039] The bottom of the base body 11 can be quickly magnetically attracted to the surface of the object to be measured through the magnetic block 14 .

[0040] like Figure 4-Figure 7 As shown, the above-mentioned detachable connection mode is preferably a threaded connection, or other rotatable and fastened connection modes. Therefore, when the sealing plate 4 needs to be disassembled, it can be rotated and disassembled by the rotating block 48 arranged above the sealing plate 4.

[0041] A spiral ring 46 is extended outward in a spiral manner above the sealing plate 4, and a slot 47 capable of engaging the wire 5 is opened downward from the upper surface of the spiral ring 46. After the wire 5 passes through the through hole 41, the excess wire 5 can be engaged to the inside along the slot 47 in a spiral manner, which has the effect of tightening and limiting. At the same time, the limit installation is neatly distributed to prevent the wire 5 from being entangled.

[0042] like Figure 5-Figure 7As shown, a fastening column 42 extends upward from the opening above the through hole 41. At the same time, the fastening column 42 is independently distributed in multiple groups, and a tightening ring 44 is also provided on the outer circumference of the fastening column 42. The tightening ring 44 is threadedly connected to the fastening column 42. At the same time, the diameter of the fastening column 42 is slightly smaller than the diameter of the wire 5. As the tightening ring 44 continues to rotate, the opening diameter of the fastening column 42 can be tightened, and then the outer surface of the wire 5 can be wrapped, which immediately has a certain tightening and waterproofing effect.

[0043] A telescopic column 43 is provided at the sealing plate 4 below the tightening ring 44, and the end of the telescopic column 43 extends to the inside of the telescopic cavity 45 opened in the tightening ring 44. At the same time, the telescopic cavity 45 is formed by extending upward from the bottom of the tightening ring 44, so that after the tightening ring 44 rotates and rises, it can also achieve a certain waterproof effect through its telescopic column 43 and the tightening ring 44. And when the wire 5 needs to be replaced, at this time, by rotating the tightening ring 44, the diameter of the fastening column 42 can be expanded, and then the wire 5 can be pulled, so that the wire 5 can be replaced, and it can achieve a certain waterproof effect after tightening.

[0044] The wire 5 between the temperature sensor 3 and the main board 22 passes through a conductive slip ring 51 to prevent the wire 5 from getting tangled when rotating and to keep the wire 5 unobstructed.

[0045] A working principle of a temperature vibration sensor: when the ambient temperature of the temperature vibration sensor is installed is high, the upper cover body 2 can be disassembled at this time, and then the upper cover body 2 and the main board 22 can be installed at a position where the ambient temperature is relatively low, and the temperature sensor 3 inside the base body 11 can be sealed and isolated by the sealing plate 4 arranged above the base body 11, thereby further improving the protection of the temperature sensor 3 after its disassembly and separation. At the same time, after the wire 5 passes through the through hole 41, its excess wire 5 can be engaged to the inside in a spiral manner along the card slot 47, which has the effect of tightening and limiting, and prevents the wire 5 from being entangled. When the wire 5 needs to be replaced, by rotating the tightening ring 44, the diameter of the tightening column 42 can be expanded, and then the wire 5 can be pulled, so that the wire 5 can be replaced, and after tightening, it can have a certain waterproof effect.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
